ADG734BRUZ

The ADG734BRUZ is a low voltage, CMOS quad SPDT (single pole, double throw) analog switch from Analog Devices. It contains four independently selectable SPDT switches configured as 2:1 multiplexers. The device is designed for general-purpose analog and digital signal switching applications.

Key electrical specifications include a maximum on resistance of 4.5 ohms with a typical value of 2.5 ohms, on resistance flatness of 0.5 ohms typical, and low leakage currents of 100 pA. The switch offers fast switching times with a typical turn-on time of 21 ns and turn-off time of 10 ns. It provides a -3dB bandwidth of 200 MHz and crosstalk of -67 dB at 1 MHz. Charge injection is 5 pC typical, and channel capacitance is 11 pF.

The device operates from a single supply range of 1.8 V to 5.5 V or dual supplies of ±2.5 V. It features guaranteed break-before-make switching action to prevent momentary shorting when switching channels. Power consumption is typically less than 0.01 µW.

The ADG734BRUZ is offered in a 20-lead TSSOP package (20-TSSOP, 0.173" width) for surface mount assembly. The operating temperature range is -40°C to +85°C.
